Spletsample size is required for a two-tailed test than for a one-tailed test. Different sample size formula are required depending on the research underlying statistical test, for example a t-test for comparing two means, a z-test for comparing two proportions or a log-rank test in time to event analyses. The sample size formula provided in this paper SpletA smaller sample size doesn’t necessarily mean a useless survey, but does restrict the amount of analysis possible. For example, you might be able to analyse fewer subgroups (see section 2.3), be less confident in your findings, or have less precise results (see section 4). Of course, larger sample sizes also cost more money.
